Manchester City winger Leroy Sane has been surprisingly omitted from Germany's final 23-man World Cup squad.
Sane was a key member of a City side who won the Premier League title with a record 100 points and was named the PFA Young Player of the Year.
Sane, who scored 10 goals and provided 15 assists in 28 games for City during the season, was one of four players who failed to make the final cut, along with Bernd Leno, Jonathan Tah and Nils Petersen.
Asked about Sane's omission, Low said: "It was a very tight decision between him and Julian Brandt (of Bayer Leverkusen) which went in favour of Brandt.
"There are better days in the life of a national team coach, when you have to send four amazing players, who deserve to be at the World Cup, home.
